CAT3604V Datasheet | onsemi

4-Channel LED Driver with Open/Short LED Detection Description The CAT3604V is a high efficiency fractional charge pump that can drive up to four LEDs with input supply voltages as low as 2.5 V. An external RSET resistor is used to control the LED channel brightness while channel diagnostics include automatic detection for both short and open LED channel conditions, ensuring the CAT3604V maintains the highest efficiency level in all operating modes. Each operating mode uses a constant high frequency switching scheme which allows the use of small form factor external ceramic capacitors while delivering excellent low noise input supply ripple up to 5.5 V. The EN input control...
